The rope light consists of an inner layer and an outer layer. LED lights are installed in the inner layer. In order to provide a direct current power supply to the LED lights, the structure of the current product is connecting an independent product, a rectifier, to one end of the inner layer and the outer layer. As such, the present product is suffering from the following defects: 1. the corresponding rectifiers have to be manufactured at the same time as the manufacturing of the rope lights, thereby increasing the manufacturing procedures and the production costs; 2. due to the fact that the rectifier is connected to the rope light in the exterior, the water-proof effect of the junction is not satisfactory; 3. due to the fact that the rectifier is connected to the rope light in the exterior, the structure of the rope light is not at all compact and the overall appearance is not very nice. In order to overcome the above defects, the inventor has designed this utility model.

In order to achieve the objectives mentioned above, this utility model adopts the following technical formula: a kind of rope light consisting of an inner layer and an outer layer covering the surface of the inner layer. There is a vertical hole in the interior of the mentioned inner layer. A number of LED lights are placed in the vertical hole. A bus connector with a positive electrode and a bus connector with a negative electrode are placed along the direction of the vertical hole in the walls of the inner layer. Two rectifying diodes are placed at the two ends of every LED lights inside the vertical hole. The positive electrode of one end of the two rectifying diodes is connected to the positive electrode of a bus connection and the negative electrode of a bus connector respectively. The negative electrode of the two rectifying diodes on this end is connected to form a positive direct current power supply, and then connect it with the positive electrode of the LED lights. The negative electrode of the other end of the two rectifying diodes is connected to the positive electrode of a bus connection and the negative electrode of a bus connector respectively. The positive electrode of the two rectifying diodes on this end is connected to form a negative direct current power supply, and then connect it with the negative electrode of the LED lights.

A male connector and a female connector have been installed at the two ends of the inner layer and the outer layer at the exterior of each of the LED lights.

The mentioned LED lights are made up of several series of LEDs.

The mentioned inner layer is made by the extrusion of thermoplastics by a mode extruder.

The beneficial effects of this utility model are:

-   -   1. Since the four rectifying diodes are installed inside the         vertical hole of the inner layer, during the manufacturing         process of the product, the four rectifying diodes are placed in         the vertical hole at the same time as the LED lights after         connecting the two. This makes the production of a rope light         with rectifier much more convenient and avoids the need to         connect the rectifier separately like the present products, and         thus with the benefits of less manufacturing procedures, lower         production costs, good water-proof effect, a compact structure         and nice appearances.     -   2. The length of the rope light can be increased by connecting         the male connector with the female connector of the different         rope light.

See Diagram 1-3. This utility model is a kind of rope light consisting of an inner layer (1) and an outer layer (2) covering the surface of the inner layer (1). The mentioned inner layer (1) is made by the extrusion of thermoplastics by a mode extruder. There is a vertical hole (11) in the interior of the mentioned inner layer (1). A number of LED lights (3) are placed in the vertical hole (11). A bus connector with a positive electrode (4) and a bus connector with a negative electrode (5) are placed along the direction of the vertical hole (11) in the walls of the inner layer (1). Two rectifying diodes (6) are placed at the two ends of every LED lights inside the vertical hole (11). The positive electrode of one end of the two rectifying diodes is connected to the positive electrode of a bus connection (4) and the negative electrode of a bus connector (5) respectively. The negative electrode of the two rectifying diodes on this end is connected to form a positive direct current power supply (7), and then connect it with the positive electrode of the LED lights (3). The negative electrode of the other end of the two rectifying diodes is connected to the positive electrode of a bus connection (4) and the negative electrode of a bus connector (5) respectively. The positive electrode of the two rectifying diodes on this end is connected to form a negative direct current power supply (8), and then connect it with the negative electrode of the LED lights (3). The mentioned four rectifying diodes form a rectifier and provide direct current power supply to the LED lights (3). Since the four rectifying diodes are installed inside the vertical hole (11) of the inner layer (1), during the manufacturing process of the product, the four rectifying diodes are placed in the vertical hole (11) at the same time as the LED lights (3) after connecting the two. This makes the production of a rope light with rectifier much more convenient and avoids the need to connect the rectifier separately like the present products. As such, this utility model possesses the advantages of less manufacturing procedures, lower production costs, good water-resistant effect, a compact structure and nice appearances.

Due to the different needs of the customers, they may require rope light of different lengths. In order to satisfy the needs of the customers to adjust the length of the rope light, this product is made up of a number of units. A male connector (9) and a female connector (10) have been installed at the two ends of the inner layer (1) and the outer layer (2) at the exterior of each of the LED lights (3). The length of the rope light can be increased by connecting the male connector (9) with the female connector (10) of several rope lights when needed. When the rope light is connected to a power source, it can be connected through connecting the female connector (10) with the plug of the male connector, and through connecting the plug and the power source, it provides alternating current power supply to this product.
